Eunji was then revealed to be a stylist in disguise, while the members discovered traces of potassium cyanide,in addition to a note matching her handwriting. To this, Eunji explained, "I really wanted to commit the murder. I even sprayed potassium cyanide on the writer's keyboard. You may all think I'm the one who killed the writer, but that's not true."

In the end, Jang Jin was behind bars after receiving a total of 4 points, causing the bomb to shut down.
